摘要：
A fuel injection nozzle for directly injecting fuel into a cylinder of an internal combustion engine is inserted in a connecting pipe extending from a fuel rail and is fixed to the connecting pipe by fastening member. The fuel injection nozzle has a sealing part for sealing a fuel passage to prevent fuel leakage, and a contact part in contact with the fastening member. The contact part is softer than the fastening member, and the contact part undergoes plastic deformation when a bending moment that bends the axis of the fuel injection nozzle acts on the fuel injection nozzle.
